Worked Solution & Example Answer:Name TWO products extracted from donated blood, and state their uses - HSC - SSCE Biology - Question 18 - 2001 - Paper 1
Step 1
Name TWO products extracted from donated blood, and state their uses.
Answer
-
Plasma: Plasma is the liquid component of blood that carries cells and proteins throughout the body. It is often used in medical treatments for patients with clotting disorders and burns, as well as to replenish blood volume.
-
Red Blood Cells: These cells are responsible for transporting oxygen from the lungs to the rest of the body. They are commonly used in transfusions for patients suffering from anemia or after surgeries.
Step 2
Propose ONE reason why scientists have now begun to develop artificial blood.
Answer
A significant reason scientists have begun developing artificial blood is the shortage of donated blood. The demand for blood transfusions often exceeds the supply available from donors, prompting research into alternatives that could provide safe and effective options for patients in need.
